Abstract

The utility model relates to a double offset ring spanner with a safety locking function and mainly solves the problem in the prior art that the double offset ring spanner is liable to slip and cause finger injury. The double offset ring spanner is characterized in that three handles (1) are uniformly distributed on the outer side of a main body (3), the bottom of the main body (3) is raised from the handles (1), three screw holes are uniformly distributed on the side wall of the main body (3) and alternated with the handles (1), and lock screws (2) are arranged inside the screw holes. The double offset ring spanner with the safety locking function has the characteristics of safety, low risk of falling off and labor-saving effect.

Description

The safety locking pin double offset ring spanner

Technical field

The utility model relates to aid used on a kind of oil field, a kind of specifically safety locking pin double offset ring spanner.

Background technology

Oil pumper is when running well production at present, need regular adjustment stroke parameter and change crank pins, in the operation of tightly unloading oil pumping machine crank pin crown type nut, often can use double offset ring spanner, because the operating space is narrow and small, the spanner of using is a handle, in the operation of tightly unloading crown type nut, the hand steered spanner of a human must be arranged, the big hammering pinch bar of another human, because spanner is a handle, therefore to often change angle,, cause personal injury so hold up the staff of spanner to be easy to be injured by a crashing object by sledgehammer, if do not hold up spanner, then spanner easily comes off; In the process of tightly unloading crank pins crown type nut, it is not in place that nut tightly unloads in addition, causes crank pins loosening, and crank pins and liner wear damage, and cause the generation of turning over the machine accident when serious, and waste time and energy.

Summary of the invention

In order to overcome the problem that existing double offset ring spanner easily comes off, easily injures finger by a crashing object, the utility model provides a kind of safety locking pin double offset ring spanner, and this safety locking pin double offset ring spanner has safety, difficult drop-off, labour-saving characteristics.

The technical solution of the utility model is: a kind of safety locking pin double offset ring spanner, comprise main body, handle, and the main body outside is evenly equipped with 3 handles, and bottom part body protrudes from handle, alternate uniform 3 screws with handle on the main body wall, screw is built-in with lock-screw.

The utlity model has following beneficial effect: owing to take such scheme, between 3 handles of this spanner three lock-screws are arranged, during the dismounting workpiece, lock-screw withstands workpiece, and then spanner need not hand steeredly can not come off yet, and because handle is 3, need not adjust angle, time saving and energy saving.Simultaneously, bottom part body protrudes from handle, like this, just can avoid hurting following workpiece when sledgehammer is pounded, and is safe in utilization, reliable.

Description of drawings:

Accompanying drawing 1 is a structural representation of the present utility model;

Accompanying drawing 2 is the cutaway views along A-A among Fig. 1.

1-handle among the figure, 2-lock-screw, 3-main body.

The specific embodiment:

The utility model is described in further detail below in conjunction with accompanying drawing:

By Fig. 1, shown in Figure 2, a kind of safety locking pin double offset ring spanner comprises main body 3, handle 1, main body 3 outsides are evenly equipped with 3 handles 1, and handle 1 is an one with main body 3, and main body 3 bottoms protrude from handle 1, be the thickness of the thickness of handle 1 less than main body 3, like this, hurt bottom workpieces in the time of can avoiding pounding spanner with sledgehammer, on main body 3 sidewalls with handle 1 alternate uniform 3 screws, screw is built-in with lock-screw 2, during the dismounting workpiece, lock-screw 2 can withstand workpiece, prevents that spanner from coming off.

When this spanner uses, earlier lock-screw 2 is screwed out, wrench body 3 is enclosed within on the workpiece, then lock-screw 2 is tightened, withstand the workpiece sidewall, at this moment can pound and dismantle workpiece with hand turning handle 1 or with sledgehammer.This spanner is compared existing spanner, uses saferly, laborsaving, and can not come off, and a people just can operate.

Claims

1. safety locking pin double offset ring spanner, comprise main body (3), handle (1), it is characterized in that: main body (3) outside is evenly equipped with 3 handles (1), and main body (3) bottom protrudes from handle (1), alternate uniform 3 screws with handle (1) on main body (3) sidewall, screw is built-in with lock-screw (2).
